Cleaning Small Parts

[Woody213]

I was wondering how people clean the insides of small copper double screws. I cant seem to get them real good. I have sat and tried pushing ketchup, cleaner etc into them but it soesnt seem to work very well

Run the inner screw in and out while both are smothered in ketchup the force the ketchup into the inner threading. Get the air out and the ketchup in. Let sit 5 minutes and rinse.

I don't know what kind of screw you are talking about . But I would try soaking in warmed vinegar or Hot soapy water. Kethup might remove tarnish just fine, but leave tomato and sugar behind as residue. If you are cleaning the inside of a hollow screw try scrubbing it with some string or yarn, threaded through it.

I'm not sure about copper, I'm sure you can google "best non toxic cleaner for copper parts" and come up with something. Me, personally, I use CLR or an ultrasonic cleaner on all my mech's, series box mods, rda's, etc.
